CAN-HOLDING CLAMP;

To all whom it may comm:

Be it known that I, MAnv'L. MARSHALL, a citizen of the United States, residing at Atchison, in the county oi Contra Costa and State of California-have invented certain new and useful Improvements in Can-Holding Clamps, of which the following is a specification. I

The invention is designed for the use of housewives in the putting up of preserves, vegetables, and other articles in cans. Ordinarily the cans after being filled are hermetically sealed by securing the head thereto through themedium of wax, which is applied in a heated condition. The loosely applied head is com-- monly held in position by the operator or person attending to the sealing of the cans with;one hand, while 'with the other hand the sealing material is applied to the seam. This requires that both hands of the person sealing the can be' employed to hold the can head in position and to apply the sealing material to the seam thereof. The objection to this manner of securing the. head to the can is that during the operation of applying the sealing material, the loosely applied head often slips from its position, which results in an improperly sealed or leakycan.

The object of the present invention is to provide a simple and inexpensive device for positively holding the head to the filled can during the operation of sealing the can hermetically, so that the person attending to the sealing of the cans may have free use of the hands. The construction of the device is such that the can may be freely rotated or turned while the sealing material is being applied to the seam thereof in order that an unsealed portion thereof may be brought immediately beneath the flow of the sealing material. As the head is positively held to the filled can, slippage or displacement the'reof during the operation of sealing is absolutely prevented.

To comprehendthe invention reference should be had to the accompanying sheet of drawings, -wherein Figure 1 is a perspective view of the holder with .a can held therein and the head in position for sealing,

the holder being illustrated as attached to an ordinary I head is mountedior free horizontalrotation on the fixed Specification of Letters Patent. Application filed March 29,1907. Serial No- 866.817.

Patented Aug. 6. 1907.

The diameter of the hircularclamp 'head4 is slightly formed with a peripheral edge flange 9, within which seats the bottom edge of the can 10, and by'means of which the said can is heldagainst displacement-.

' greater th'an'that of the can to be filled, andthe same is Through the outwardly extended end or overhang I portion 3 of the bracket arm 2, works the screw-threaded stem 11 -This stem at its lower end portion carries the rotatable clamp head 12, whichclamp head is considerably smaller than the lower clamp head 4, and the same is designed to bear centrally on the can head 13 to be united to the open end of the filled can 10. Said clamp head 12 is held to'the stem 11 by means of the pins 14, which-extend through the head 12 and project within a circumferential groove 15 on the lower portion ofthesaidstemll. v

The clamp head 12 is a vertically adjustable one,-

while the lower clamp head 4 is held against vertical movement. Said clamp head 12 is adjusted toward and from the lower clamp head 4 by means of the screwthreaded stem 11, which-stern is turnedby means of the finger piece 16 forming a portion thereof.

, The filled can to be sealed is placed on the rotatable head 4, the can head 13 loosely applied thereto and the stem 11 lowered until the clamp head 12 bears firmly clamp head 12 away frorn'th'e can head 13, so as to release the sealed vcan and permit of its being removed from its seat on the lower horizontally rotatable clamp head 4 and placed to one side. The holder is then free to receive another filledcan to be sealed. In order that the device may be secured to the edge of a table, a clamp arm 17 is hinged to the bracket arm 17, said clamp arm being formed with an inwardlypro jecting extension 18, which, when the arm 17 -is thrown downward, comes below the edge of the table, Fig. 1 of the drawings. Through this extension 18 works the screw-threaded clamp rod 19, the head 20 of which when 'the clamp rod is screwed up bears against the under face of the edge of the table to clamp the holding I device thereto.

Having thus described the invention what is claimed as new and desired'to be protected by Letters Patent is- I 1. In a. device for the hoidingof filiedcans during the operation of sealing a loosely applied head thereto. the combination with a suitable base, of a bracket arm. upwardly springing therefrom, said bracket arm being formed with a forwardly extended overhang portion, of a screwtln-eaded adjustlng stem working through the gu'erluing portion of the bracket arm, of a clamp headiohiiubly connected to the adjusting stem, of a stud centrally protherefrom, said bracket arni being formedwith a forwardly extended overhang portion, of a screw-threaded adjusting stun working through the overhang portion of the bracket arm, of a clamp head rotatahly connected to the adjusting stem, of a stud centrally projecting from the base plate,

of a clamp head secured to the said stud 01 horizontal rotation, and of means for clamping the holding device to a table or platform, said means comprising a hinged clamp arm and a clamp screw working therethiough.

In testimony whereof I have signed my name to this specificatiori in the presence of two subscribing witnesses.
